Table 4: This table sums up, for all objects within 3 different size ranges, the respective amount of mass that is removed by all cratering and all fragmenting impacts. These values are obtained in the steady state regime for the nominal case.

Size range (cm)		0.01<R<1	105<R	total
Fraction of
mass removed:
by fragmentation	0.89	0.13	0.76	0.67
by cratering	0.11	0.87	0.24	0.33
